Patient is giving me jewelry. What should I do?

My boss has ostomy & parkinson disease. She has no child. Her husband died a year ago. she doesnt have any relatives or if she have, she doesnt want to get involved with them. I tried to encourage her to reach out with them but always end up into arguments. Telling me that she gave them their part & so. I does all the paper works for her, setting appointment with her accountant & filing her assets, utulility bills & statements of accounts. I also help her with phone calls if she need to make one. In short, i'm like her secretary. and then one day, she asked me to open all her cabinet to look through her closet. To make the story short, she have a box of jewerly. She wants to give it to me so I can give it to my daughter. I told her not to and give it to her relatives or a friend that deserve more that I nor my child. I told her that I'm afraid that when she's gone& someone will sue me accusing of stealing it. She said to me with tearly eyes that she doesnt have any relatives & those are her personal things & she wants me to have as a gratitude of helping her. There's a circumtances that shes begging me to have it because she afraid that someone get it when shes gone. Someone adviced me to take it, because its her will. And just ask her to make a letter as proof that she gave that to me with her signature. But im so scared & afraid. Can someone help me with this? Should i take it? If I will take it, is there any legal advice? Thanks
